Full honeycomb board wind power generator wind wheel blade

Abstract

A wind turbine blade fully made of honeycomb boards comprises a housing and an internal support structure. The housing is mainly formed of an upper half housing and a lower half housing. The internal support structure is arranged in the housing, and connected to support portions of the upper half housing and the lower half housing respectively. The upper half housing is formed by bending a first honeycomb board (1). The lower half housing is formed by bending a second honeycomb board (2). The internal support structure is a longitudinal support board (3). The longitudinal support board is formed of a vertical honeycomb board (30). The longitudinal sections of the longitudinal support board and the housing at the support portions have the same shape and match in size. The blade structure reduces the weight of the wind turbine blade, increases the wind-to-power conversion efficiency of the wind turbine, simplifies the process of using the honeycomb boards to manufacture the wind turbine blade, and reduces the manufacturing costs.

Description

technical field [0001] The invention relates to a wind turbine blade of a wind generator, in particular to a wind turbine blade made of a full honeycomb board. Background technique [0002] The known wind turbine blades are generally made of glass fiber mixed with resin. Due to the problems of heavy weight, high brittleness, and harmful gas release during production, the wind rotor blades made in this way have light specific gravity and have Wind rotor blades with good fatigue strength and mechanical properties have become an important issue in the innovation of wind turbines. Because of their light specific gravity, high strength-to-weight ratio, average force, strong pressure resistance, good shock resistance and no deformation, honeycomb panels are ideal for manufacturing wind turbines. It is an excellent material for wind turbine blades for power generation, but due to the structural characteristics of honeycomb panels, it is quite difficult to process and combine them i...

[0002] The known wind turbine blades are generally made of glass fiber mixed with resin. Due to the problems of heavy weight, high brittleness, and harmful gas release during production, the wind rotor blades made in this way have light specific gravity and have Wind rotor blades with good fatigue strength and mechanical properties have become an important issue in the innovation of wind turbines. Because of their light specific gravity, high strength-to-weight ratio, average force, strong pressure resistance, good shock resistance and no deformation, honeycomb panels are ideal for manufacturing wind turbines. It is an excellent material for wind turbine blades for power generation. However, due to the structural characteristics of honeycomb panels, it is quite difficult to process and combine them into the shape of wind turbine blades, making it impossible to promote the use of honeycomb panels to manufacture wind turbine blades.
